Improve Cookie and Site Data Management

Improve Cookie and Site Data Management

Content:
Firefox already has cookie management tools, such as “Manage Data” and “Exceptions,” but the current system feels separated and less practical than it could be.

I think Firefox could improve the experience by combining these features into a more comfortable and streamlined cookie management system.

For example, when users manually select cookies or site data they want to keep, Firefox could automatically remember those choices as permanent allowed entries for future cleanups. This would avoid the need to repeatedly configure exceptions or manually reselect important cookies every time browsing data is cleared.

The idea is to make cookie management faster, simpler, and more intuitive:

Keep important cookies automatically
Remove unwanted cookies more easily
Reduce repetitive manual work
Make privacy management more user-friendly

This would especially help users who regularly clear browsing data but still want to preserve logins, preferences, or trusted websites without having to configure multiple separate sections.

I totally agree with you and think this is a much needed feature.

I searched on Github and found some interesting Addons:

- https://github.com/Perruer/cookietin (new)
- https://github.com/Rob--W/cookie-manager
- https://github.com/j127/auto_delete_cookies_for_privacy

And of course, I did use https://github.com/cookie-autodelete/cookie-autodelete in the past, but it isn't maintained anymore and a native implementation would be awesome.

Author of CookieTin here (one of the add-ons mentioned above), so treat this as a biased but informed comment.

The "remember what I chose to keep" part already exists outside the browser: CookieTin lets you mark individual cookies as protected, and its cleanup — on a timer or at startup — skips them. It also puts them back if a site or a manual cleanup removes one. So the workflow Jeico008 describes is doable today; the problem is that it takes a third-party add-on to get it.

One thing worth adding to the request, because it affects any native implementation: cookies stored in a partition (Total Cookie Protection in Firefox, CHIPS in Chrome) are invisible to the normal listing. In the WebExtensions API, cookies.getAll() skips them unless you pass partitionKey: {}, and cookies.remove() won't find them without the exact partition key. Firefox's own "Manage Cookies and Site Data" doesn't surface them either, which is why people report "I deleted everything and the site still recognises me".

A native manager that merges the existing panels but keeps that blind spot would leave the most annoying case unsolved. Whatever shape this takes, please make partitioned and container cookies first-class in it.
